Paypal GetExpressCheckoutDetails 缺少 PAYERID

Question

(参见 https://developer.paypal.com/docs/integration/direct/identity/seamless-checkout/)

1. 我们通过 OpenID(使用 PayPal 登录)让用户登录并接收访问 token 。
2. 我们调用 SetExpressCheckout 给出 IDENTITYACCESSTOKEN
3. 我们调用 GetExpressCheckoutDetails 并期望填充 PAYERID。它不存在于响应中。

没有 PAYERID，我无法调用 DoExpressCheckoutPayment。

我在下面附上了请求/响应数据。请注意，GetExpressCheckoutDetails 不包含 PAYERID。为什么会发生这种情况？

谢谢!

即使您在 SetExpressCheckout 调用中传递了 IDENTITYACCESSTOKEN，您仍然需要将买家重定向到 PayPal，以便他们可以批准付款。设置 IDENTITYACCESSTOKEN 允许买家跳过登录页面，使他们的流程更快，但他们仍然需要转到 PayPal 以批准付款。调用 SetExpressCheckout 后，将它们重定向到 https://www.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token={token}(其中 {token} 是来自 SetExpressCheckout 响应的 TOKEN 的值。
